Is it permissible to kiss one's maternal aunt?

Question:
In her third question, she asks: Is it permissible for my son to kiss my maternal aunt?

Answer:
Your maternal aunt is his maternal aunt, the sister of his mother, and the sister of his grandmother is also his maternal aunt. He may kiss her on the head, between the eyes, or on the cheek. As for the mouth, it is better to leave it alone; the mouth is for the wife and young children. Kissing an older woman should be on the head, between the eyes, or on the cheek.
